Patented July 27, 1909.

Application filed AprI 5, 1909. Serial No. 488,008.

To all whom it may concern:

Be it known that I, ROBERT J. HARDiNG, a citizen ol' the United States, residing at Poughkeepsie, in the county oi Dutchess and State of New York, have invented new and use'l'ul Improvements in Split' T-Valves, of which the following is a speciication. ,j

This invention relates to improvements in split tee valves.

The object el the invention is to provide a valve having a split or separable casing, whereby the same may be readily applied to a pipe without removing the same7 and having means whereby a branch pipe may be connected by said vcasing to the main pipe.

A further object is to provide an improved l'orm oil valve disks, and means for operating the same. i

/Vith the foregoing and other objects in view, the invention consists of certain no vel features of construction, j combination and arrangement ol' parts, as will be more fully described and particularly pointed out in the appended claims. j

In the accompanying drawings: Figure 1 is a side view of a valve constructed in accordance with my invention. central .vertical sectional view of the same on the line 2 2 ol Fig. 3. Fig. 3 is a horizontal sectional view on the line 3-3.ol' Fig. 1.

In the embodiment ol' my invention l provide a casing 1 comprising a lower section 2, and an upper section 3, the body portions of which when placed together l'orm a rectangular casing. upper and lower sections are formed semicylindrical oi half socket members 4 which when the sections are brought together form sockets which engage the ends of the pipe to` which the valve is applied. rlhe socket members 4 are provided with laterallypio-A jecting apertured langes bolted around the pipe. The socket members after being thus engaged with the ends of the pipe are calked into fluid tight engagement therewith. y j

In addition to the socket members 4.the upper and lower sections of the casing are provided on one side with additional upper` and lower semi-elliptical socket members 6, which are provided with lateral apertured ilanges 7 adapted to be bolted together, as shown. The outer ends of the side socket members 6 are further provided with radial langes 8, whichl when the socket members are brought together l'orm an elliptical flange( Fig. 2 is f3 of the drawings.

creased thickness of the valve disks will be` On the opposite ends of the 5, which. are

which is provided with a series ol' bolt holes to receive the clamping bolts 9 of a removable stop or closing plate 10, whereby the side socket may be closed when not em; ployed iorconnecting a' branch pipe with the main pipe. j

In the side of the upper member 3 of the casing is formed an opening 11 which is preferably of oblong rectangular shape and isA surrounded by a vert-ical projection 12, having on its upper end a laterally projecting flange 13, provided with a series oi bolt holes. On the upper end of the projections 12 is bolted a rectangular hollow dome14, in the upper end oi' which is formed a guide passage ,15 and to said upper end is secured a stu'fling box 16.

` In the inner walls of the upper and lower sections oiI the valve casing are formed recesses or valve seats 17 with which communicate similar seats 18 formed in the inner side walls of the dome 14. Slidably mounted in the seats 17 and 1S of the casing and dome are elongated valve disks or plates 19 which are preferably formed of greater thickness at their edges adjacent to the branch connection or" the casing, as is clearly shown in Fig.

The purpose of this inhereinaiter described.

Between the disks vat the lower portions thereof is arranged an expanding block 20, which is vloosely connected to the disks by means of lugs 21 formed on the inner sides of the disks, and which are adapted to engage elongated recesses 22, formed inthe opposite sides of the block, as shown. is provided with a taperedor wedge-shaped upper end as clearly shovmy in Fig. 2 ofthe drawings. Between the valve disks above the expanding block 20 are disks clamping wedge blocks 23, the innerr sides of which adjacent to their lower edges are beveled or inclined at 24 to engage the wedge-shaped upper end of the expanding block 20, whereby when said wedge blocks are forced downwardly, said upper end of the expanding block will Vforce the wedge blocks laterally, thereby Vcrowding or clamping the disk plates into fluid tight engagement with their seats.

Between the valve disks Vabove the wedge blocks 23 is arranged an interiorly threaded The block 20 :35-I l down' in t 5.0.. auch forming notaires o of greater r recesses 27 25 is engaged the threaded valve operating rodf o :1-Jects"'upwardlyfthrollgll the. dome and the aperture 1;.57` and. th
